Abstract: A method, electronic device, computer program product, system and circuit assembly are provided for allocating one or more redundant pictures by taking into consideration the information content of the primary pictures, with which the redundant pictures would be associated. In particular, primary pictures that are determined to be more sensitive to transmission loss or corruption may be allocated one or more redundant pictures, while those that are less sensitive may not be so allocated. By selectively allocating redundant pictures to only those primary pictures that are more sensitive, the method disclosed reduces the amount of overhead associated with redundant pictures and increases the coding efficiency, without sacrificing the integrity of the video data.

Abstract: A method for reporting a streaming quality is shown, wherein at least one continuous media stream is streamed to a client (601), and wherein the streaming is controlled by a protocol (109) that is operated between the client (601) and a server (600), the method including selecting at least one quality metric and a quality metrics class from a pre-defined set of at least two quality metrics classes, and reporting to the server (600) the quality of the streaming based on the at least one selected quality metric and the selected quality metrics class. The protocol (109) is preferably a Real-time Streaming Protocol (RTSP) in combination with a Session Description Protocol (SDP) in the context of the 3GPP Packet-Switched Streaming Service (PSS). Also shown is a computer program, a computer program product, a system, a client, a server and a protocol.
